Consider these bicycles (both mine). This one:

is the school track star. Lean, sleek, fast, not an extraneous ounce of fat. Guys want to be him, girls want to be with him.

This one:

is the kid in your math class with taped up coke bottle glasses and a pocket protector in his polyester shirt with the top button done up. Smart, practical, will probably have a well-paying job someday, but he ain't dating a cheerleader.

Discuss.
